docs: def declareAsOntology(self, graph):
          """
          The file we output needs to be declared as an ontology,
          including it's version information.
  
          TEC: I am not convinced dipper reformating external data as RDF triples
          makes an OWL ontology (nor that it should be considered a goal).
  
          Proper ontologies are built by ontologists. Dipper reformats data
          and anotates/decorates it with a minimal set of carefully arranged
          terms drawn from from multiple proper ontologies.
          Which allows the whole (dipper's RDF triples and parent ontologies)
          to function as a single ontology we can reason over when combined
          in a store such as SciGraph.
  
          Including more than the minimal ontological terms in dipper's RDF
          output constitutes a liability as it allows greater divergence
          between dipper artifacts and the proper ontologies.
  
          Further information will be augmented in the dataset object.
